' To all whom it may concern:

Be it known that we, JAMES SAMUEL FOLEY, residing at 5 High street, WestBromwich, in the county of Stafford, England, engineer, and FREDERICKWILLIAM BAKER, residing at 59 Hagley road, Stourbridge, in the county ofWorcester, England, engineer, subjects of the Kingdom of Great Britain,have invented certain new and useful Improvements in or Relating toDetachable or Interchangeable Wheels for Motor- Vehicles and the like,of which the following is a specification.

This invention relates to detachable or interchangeable wheels for motorvehicles and the like, of the type comprising a permanent or inner hubable hub or member adapted to encircle or be carried by the saidpermanent or inner ub or member, and 'a retaining member adapted tobe'screwed upon the permanent hub or member, and to retain thedetachable hub or member in relation thereto.

The present invention has for its purpose to provide aparticularlysimple and eflicient mode of and means for locking theretaining member when in its engaged position.

The present invention has, furthermore, for its purpose to provide forthe withdrawal of the detachable hub or member from the permanent hubor.member by or through the medium of the retaining mem-" ber in aparticularly satisfactory manner.

The retaining member is screwed upon the permanent hub or member, and inthe present invention the screwed connection may be the same hand, inthe case of all the wheels of the vehicle. The locking member accordingto the present invention, operates by virtue of a screw, and this alsomay be of the samehand in connection with all of the wheels of thevehicle, so that any detachable hub or-wheel pertaining to the vehiclemay be assembled in relation to any permanent hub of the vehicle in thesame manner, and by the same operation.

According to the present inventlon, the retaining member takes the formof a cap or ring adapted to be screwed upon the outer extremity of thepermanent hub, and to engage with the detachable hub 1n a manner wherebywhen the retaining member is screwed up, the detachable hub or member isappropriately retained in relation to the permanent hub or member.

or member, a detach-- explanatory A locking ring or member for lockingthe retalnlng member is screwed upon the latter, and is adapted toengage with the detachable hub or member, advantageously indirectly,through the medium of an intermediate member or members. Thisintermed1ate member, or these intermediate members, may be convenientlyin the nature of a washer or of sections of a washer adapted to havesuch a connection with the detachable hub or memberthat it or theycannot rotate in relation to the latter, and said intermediate membersare adapted to be glripped between the locking member and a s oulder orenlargement provided uponthe retaining member.

After the retaining member has been screwed up, the locking membertherefore is screwed up, and thus the intermediate member or memberswhich are coupled to the detachable hub or member are gripped betweenthe locking member and theshoulder upon the retaining member. The usualdrive members are provided upon the permanent and detachablehub membersso that the detachable hub cannot rotate in relation to the permanenthub. Should the retain ing member tend to unscrew, the locking membercarried thereby, being in frictional contact with the intermediatemember which is retained from rotation by its positive connection withthe detachable hub, thereby tends or has a tendency to screw up and thusaccidental detachment of the retaining member is avoided.

In order that this invention may be clearly understood and readilycarried into practice, reference may be had to the appended sheet ofdrawings, upon which Figure 1 is a part-sectional elevation of a mainand detachable hub combination according to the present invention.

Fig. 2 is an end elevation of the part shown in Fig. 1, the ringpurposes of illustration.

Fig. 3 illustrates a modified form of the invention.

In a convenient embodiment of the present invention, and referrin toFigs. 1 and 2 of the drawings, we emp 0y a permanent hub member a havingnear its inner extremity (not shown) a cone formation, and having in itscentral part a drive formation (not shown), adapted to engage wlth asimibeing removed for or plane within the outer extremity of the lardrive formation in the central part of the detachable hub 12 whichlatter may be furnished. with a female cone formation adapted to engagewith the male cone formation occurring near the inner extremity of thepermanent hub.

The retaining member is in the form of a cap 0 adapted to be screwedupon the outer extremity of the permanent hub a, and said cap 0 has atits inner extremity a male cone (1 adapted to engage with a secondfemale cone opposed to the irst-mentioned female cone, within thedetachable hub 12.

The retaining member is of form permitting of its inner part beingpassed into the outer end of the detachable hub b, and the latter at itsouter end is furnished with an inturned flange 7, which latter isslotted, recessed, or perforated conveniently at two points in itsdiameter, as at g, g. At a' point detachable hub, the retaining member 01s radially furnished with an annular shoulder h of diameter suited topermit of its passing within the inturned flange f at the outerextremity of the detach' .ble huh 1). Against this shoulder twosubstantially semi-circular ring portions, 2', i are assembled, eachhaving a lug j, projection, rivet, or the equivalent, adapted to takeinto one of the slots,holes, or recesses g in the inward flange f at theouter extremity of the detachable hub b. The lugs j are disposed'withinthe outer contours of the semi-circular members i and said semi-circularmembers after being introduced, are of a.

character whereby they may be displaced outward to engage with the innerside of the inturned flange f of the detachable hub, and thereby providefor the withdrawal of the latter.

The locking member adapted to be screwed upon the retaining member is inthe form of a ring 70, and is furnished at its inner extremity with apart Z adapted to engage with the inner surface of the semi-circularmembers 2', so that when the locking member is is assembled, thesemi-circular members i are retained in their outermost positions inwhich they engage with the inner surface of the inturned flange f uponthe detachable hub b. The locking member is is of a character whereby itis adapted to grip the members z, '5 between itself and the enlargementit upon the retaining member 0, and the semi-circular members i beingincapable of rotation in relation to the detachable mem her I), thusserve to provide for the locking of the retaining member 0 or forpreventing accidental detachment of the latter.

If desired, the part Z of the member is may be furnished with a malecone formation, adapted, when the member is is assembled,-to force thesemi-circular members i outwardly, thereby expanding them into positionsin which they engage with the inner surface hub.

Projections k may be provided at intervals around the member is, and mayconstitute the means by which the latter is rotated. A double-endedspanner may be proof the inturned flange 7 upon the detach able vided,one end of which is adapted to provide for the release of the member is,and

after the member is has been loosened, as, r

for instance, by one complete turn, the other end of the spanner isapplied to the member 0. It is desirable when unscrewing the memberc,'to also unscrew the member is, and for this purpose the part of thespanner adapted to engage with the member 0 may be furnished with one ormore lugs or projections adapted to engage with the projections 70 uponof the members 0 and k may be screwed collectively.

Any convenient means (not shown) may be incorporated for limiting theextent to which the locking member may be unthereby un the member is sothat both screwed in relationto the retaining member, so that normallythe locking member, retaining member, semi-circular members anddetachable'hub are combined, and are adapted to be withdrawn from thepermanent hub as a combined whole.

In a modified embodiment of the present invention, shown in Fig.3,instead of the two semi-circular members, we employ a unitary which inthis case are disposed outside of the outer circle or contour of thering on, said lugs n being adapted to engage with the slots 9 in theinturned flange f of the detachable hub I).

Said ring m is of diameter permitting of its being passed through theflanged outerextremity of the detachable. hub b ring m furnished withtwo lugs n,

into engagement with the enlargement 0 upon the retaining member, but inorder, in this case, to provide for the withdrawal of the detachable hubby the retaining member, the enlargement 0 last mentioned is of diameterexceeding the internal diameter of the outer flanged end of thedetachable hub, and' in order to permitv of the passage of theenlargement 0 into the detachable hub, such enlargement 0 is providedaround only a part of the circumference, so that it can be assembled bybringing the parts into eccentric relationship, and uponthe parts beingsubsequently centralized, the ring inserted, and the looking memberassembled, the parts are retained in their concentric positions.

By this last described arrangement lit will be noted that we provide forthe with:

drawal of the detachable hub by the retaining member, and also providethat such.

ber can thus be readily used with another shell on the same permanenthub.

If desired the screw thread between the locking member I: and theretaining member 0 may be quicker or slower than the thread between theretaining member 0 and the permanent hub.

What we claim as our invention and desire to secure by Letters Patentis 1. A permanent and detachable hub combination, having a retainingmember having a screwed connection with the permanent hub and adapted toengage with the detachable hub, and a locking member having a screwedconnection with the retaining member, the locking of the retainingmember being effected by engagement of the locking member with a partwhich is iesrained from rotation in relation to the 2. A detachable andpermanent hub combination, having a screwed retaining member and alocking member screwed thereon, such locking member being adapted toengage with a member extending circumferentially. of the hub, whichmember is relatively restrained from rotation in relation to, but isaxially movable in relation to, the detachable hub.

3. A detachable and permanent hub combination having a screwed retainingmember and a locking member screwed thereon,

and substantially semi-circular members intermediate sa1d retainlngmember and said locking member, said substantially semi-circular membersengaging with the detachable hub to prevent the rotation of thesemi-circular members relatively thereto.
